使用按钮选择器禁用按钮 [英] Disable button with button selector

问题描述

我有一个按钮选择器，可以在按下按钮时更改按钮图像。我还为禁用按钮设置了图像。我尝试以编程方式禁用按钮，但是未显示禁用的按钮图像。我的button_selector是否正确？

I have a button selector that changes the button image when it is pressed. I have also set an image for when the button is disabled. I try and disable the button programmatically but the disabled button image is not appearing. Is my button_selector correct?

<item android:drawable="@drawable/red_btn_bg_disabled" android:state_enabled="false"/> <!-- disabled -->

<item android:drawable="@drawable/red_btn_bg_pressed" android:state_pressed="true"/> <!-- pressed -->
<item android:drawable="@drawable/red_btn_bg_pressed" android:state_focused="true"/> <!-- focused -->

<item android:drawable="@drawable/red_btn_bg"/> <!-- default -->

我正在使用mButton.setEnabled （false）在我的代码中以禁用按钮

I am using mButton.setEnabled(false) in my code to disable the button
